What is the percentage mass of oxygen in morphine?
The chemical formula for morphine is C17H19NO3. To calculate the percentage mass of oxygen in morphine, determine the molar mass of oxygen in the formula (3(16 g/mol)) and divide by the molar mass of morphine (285 g/mol), then multiply by 100 to get the percentage. The percentage mass of oxygen in morphine is approximately 16.8%.
How do you calculate the grams of an element in a specific amount of a compound?
To calculate the grams of an element in a compound, you need to find the molar mass of the element and the compound. Then, use the formula: (mass of element/molar mass of compound) x molar mass of element. This will give you the grams of the element in the compound.
How is the molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
What element has a molar mass of 30.974 g?
The element with a molar mass of 30.974 g is phosphorus.
Which is always equal to the molar mass of any element?
The atomic mass of an element is equal to its molar mass in grams/mol.
Which element in morphine contributes the least to the molar mass?
The formula for morphine is C₁₇H₁₉NO₃, so the element nitrogen contributes least to the molar mass.
Which element N S Pu or Cl contains the least moles of atoms in a 5.0g sample?
Number of moles = mass / molar mass, so the answer is the one with the greatest molar mass. This is plutonium.

What does an element's molar mass tell you about the element?
An element's molar mass represents the mass of one mole of that element in grams. It tells you the average atomic mass of the element, which is the sum of the protons and neutrons in the nucleus of its atoms. Molar mass helps in determining the amount of substance in moles when given the mass of the sample.
What is the molar mass potassium?
The molar mass of the element potassium is 39 g/mol.
Which is always equal to the molar mass of any element?
The atomic mass of an element is equal to its molar mass in grams/mol.
The molar mass of an element is equal to?
The element's average atomic mass.
How do you calculate the Percent composition by mass of chloroform?
To calculate the percent composition by mass of chloroform (CHCl3), find the molar mass of each element (carbon, hydrogen, and chlorine) and the total molar mass of chloroform. Then, divide the molar mass of each element by the total molar mass and multiply by 100 to get the percentage of each element in chloroform.
