Answer to Problem 48LC
The grams of hydrogen in 124 g of
Explanation of Solution
The percent by mass of each element in the compound represents the percent composition as:
The percent composition can be determined by the molecular formula of the compound as well as using the relation:
The molar mass of
The moles of Ca, C, H, and O are converted to grams of Ca, C, H, and O as:
The mass of 1 mol of
Now, determining the percent composition of
The conversion factor to convert the mass of
Now, to calculate the mass of
Hence, the grams of hydrogen in 124 g of
