as per the equation , one mole of
I can write this as ( 1 mol
I have started with 5 g of Propane. In terms of moles # of moles of propane = mass of propane / molar mass of propane
moles = (5g / 44 g
moles of propane = 0.114 moles.
0.114 moles of
I can write this as ( 0.114 mol
The two ratios are equal ( for making a cake I need two eggs and 3 cups of sugar.For making three such cakes , I will need 6 eggs and 9 cups of sugar, the ratio of sugar to flour will remain the same , it will not change with the # of cakes I want to make, but what will definitely change is the amount of the ingredients, but the ratio will stay the same.) Using the same logic the two ratios are equal.
( 1 mol
1 . x = 4 x 0.114
x = 0.456moles
0.114 moles ( or 5g ) of
one mole of water has mass 18 g /
so the amount of water actually obtained was 0.80 x 8.208 = 6.556 g.
