how many grams of hydrogen are needed to produce 1.80g of water?
606080
Another way to look at it is that the proportions of themass of hydrogen in a water molecule to the total mass of themolecule would be 2/18 . For 1.8 g of water this situation is equal to0. 2/1.8 , i.e . you need 0.2 g of hydrogen to produce 1.8 grams ofwater .

1 liter of water (l) = 1,000.00 grams of water (g wt.)

Part 1. There are 4 moles of hydrogen atoms in 36 grams of water, which is choice a.

Hydrogen gas can be prepared by reacting metallic sodium with water: 2Na(s) + 2H2O(l) → H2(g) + 2NaOH(aq). If the price of sodium were 165/kg, what would be the cost of producing 1.00 mol of hydrogen.

Chemical formula of water is H2O. Molecular mass of water(H2O) is 18gram which contains 1mole . Now, 1kg water contain 1000/18 =55.55mole .
463381
So water is 11.2% hydrogen and 88.8% oxygen by mass.

1 gram of water (g wt.) = 1.00 cubic centimeters of water (cm3 - cc)

Based on the atomic properties of water, 1 kg of hydrogen gas requires about 2.4 gallons of water as feedstock. In one year, 60 billion kilograms of hydrogen would require 143 billion gallons of fresh, distilled water.

1. There are 16 grams of oxygen in 18 grams of water. We can see from the formula for water, H2O, there are twice as many hydrogen atoms (each of atomic mass 1) as oxygen atoms (each of atomic mass 16).

In this case, the periodic table tells us there is 1g of hydrogen per mole. We know that dihydrogen (H2) has 2 hydrogen atoms per molecule, so there will be 2 * 1g hydrogen per mole = 2g dihydrogen per mole.

How many moles in 27g of water? We know that H20 is 18.015 g/mole. if 18 g is 1 mole, divide 27 by 18. 27 divided by 18= 1.5 moles.

To use our old friend water as an example: One mole of Water is composed of 1 mole of Oxygen and two moles of Hydrogen. The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

Water has a molar mass of 18.01528 g/mol≈18 g/mol . Since water has a chemical formula of H2O , there will be 2 moles of hydrogen in every mole of water.

The SI base unit for amount of substance is the mole. 1 grams Water is equal to 0.055508435061792 mole.

Roughly atoms. Water has a molecular mass of 18. 1/18 = 0.056 moles of water molecules in 1 gram of water. The molecular formula of water is H_2O so there are two hydrogen atoms per one water molecule.

Approximately how many grams of oxygen are there in 144 grams of water? Since the ratio, by mass, of hydrogen to oxygen is 2:16, then oxygen is 16/(2+16)=8/9 of mass of water. Therefore there are 144*8/9=128 grams of oxygen in 144 grams of water.

It's would take 80 cal for converting I've to water, then 100 cal for bringing water from 1 to 100 degree & finally 540 cal for converting water at 100 degree to stream. Total 720 cal needed for 1g of ice. The Brainliest Answer!
