What is the percent by mass of carbon in c10h14n2

74.07% is the percent by mass of carbon in .

Explanation:

Molar mass of compound = M

Number of carbon atom = 10

Atomic mass of carbon  = 12 g/mol

Percentage of element in compound :

Mass percentage of Carbon :

74.07% is the percent by mass of carbon in .

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
