Molarity and molar are moles per litre. % comp is exactly that, just %. Mass comp seems like it would be w/w, i.e. a percentage. I have rarely heard this term but it is the closest. The answer you are looking for is molecular mass or atomic mass.

What is the percent composition of carbon in carbon monoxide?

To find the percent composition of carbon in carbon monoxide (CO), we first determine the molar mass of CO. Carbon has a molar mass of approximately 12.01 g/mol, and oxygen has a molar mass of about 16.00 g/mol, giving CO a total molar mass of 28.01 g/mol. The percent composition of carbon is calculated as (molar mass of carbon / molar mass of CO) × 100%, which results in (12.01 g/mol / 28.01 g/mol) × 100% ≈ 42.8%. Thus, the percent composition of carbon in carbon monoxide is approximately 42.8%.


What is the percent composition by mass of iron in iron (III) chloride?

To calculate the percent composition by mass of iron in iron (III) chloride (FeCl₃), first determine its molar mass. The molar mass of Fe is approximately 55.85 g/mol, and for Cl, it is about 35.45 g/mol, giving FeCl₃ a total molar mass of approximately 162.2 g/mol (55.85 + 3 × 35.45). The percent composition of iron is then calculated as (mass of Fe / molar mass of FeCl₃) × 100, which is (55.85 / 162.2) × 100 ≈ 34.4%. Thus, the percent composition by mass of iron in iron (III) chloride is approximately 34.4%.


What is the percent composition of beryllium in Be and oxide O?

The percent composition of beryllium (Be) in beryllium oxide (BeO) can be calculated using the molar masses of the elements. The molar mass of Be is approximately 9.01 g/mol, and that of oxygen (O) is about 16.00 g/mol, giving BeO a total molar mass of roughly 25.01 g/mol. The percent composition of beryllium in BeO is then calculated as (9.01 g/mol / 25.01 g/mol) × 100%, which is approximately 36.04%.


What is the percent composition of CI in MgCI2?

To find the percent composition of chlorine (Cl) in magnesium chloride (MgCl₂), first calculate the molar mass of MgCl₂. The molar mass of magnesium (Mg) is approximately 24.31 g/mol, and that of chlorine (Cl) is about 35.45 g/mol. Thus, the molar mass of MgCl₂ is 24.31 + (2 × 35.45) = 95.21 g/mol. The percent composition of Cl is then calculated as (2 × 35.45 / 95.21) × 100%, which is approximately 74.4%.


What is the percent composition of magnesium (mg) in mg0?

To find the percent composition of magnesium (Mg) in magnesium oxide (MgO), first determine the molar masses: magnesium has a molar mass of approximately 24.31 g/mol, and oxygen has a molar mass of about 16.00 g/mol. The molar mass of MgO is roughly 40.31 g/mol (24.31 g/mol + 16.00 g/mol). The percent composition of magnesium is then calculated as (24.31 g/mol / 40.31 g/mol) × 100%, which equals approximately 60.3%.
