25x(2/18)=2.78g of hydrogen
25x(16/18)=22.22g of oxygen
25 grams H2O (1 mole H2O/18.016 grams)(6.022 X 1023/1 mole H2O)
= 8.4 X 1023 atoms of water
------------------------------------
0.50 moles of Hydrogen
250g = 8.82oz (dry)
6.6x1022 per gram of water
The answer is 900 kg.
i think that you have to add 100 gramd to produce the amount of 900 grams
45,0 grams of hydrogen gas have 135,5.10e23 atoms.
For water only, grams equals milliliters. One cup = 250mL. So, one cup = 250g
250g 250g are in one cup
250g = 8.82oz
250g
2
250g = 8.82oz
Hydrogen nitrate has a mass of 63.01 g/mol. In order to find the number of moles you divide the grams by the molar mass. 250/63.01 = 3.96 mol.
250g = 8.82oz (dry)
250g

There is about 5 cups of mini marshmallows in a 250g bag.
