What does gmol -1 mean?
The notation "gmol⁻¹" refers to grams per mole, which is a unit of measurement used in chemistry to express the molar mass of a substance. It indicates how many grams of a substance are contained in one mole of that substance. For example, if a compound has a molar mass of 18 gmol⁻¹, it means that one mole of that compound weighs 18 grams. This unit is essential for converting between the mass of a substance and the amount of substance in moles.
What compound has a molar mass of 18 grams?
Water. Remember the equation Moles = mass(g) / Mr (Relative Molecular Mass) So Molar Mass(g) is = to moles X Mr. or Mr = mass(g) /moles Since ther mass is 18 g and molar mass is 1 mole Then substitute Mr = 18g / 1 = 18 So referring to the Periodic Table. for elements with an atomic below 18 . We have oxygen at 16 and hydrogen at 1 So 16 + 1 + 1 = 18 . Hence oxygen + 2 hydrogen = water (H2O).
How many moles of water are present in 48 grams?
To find the number of moles in 48 grams of water, we first need to calculate the molar mass of water (H2O), which is approximately 18 grams/mol (1 mol of H2O = 18 grams). Then, we divide the given mass (48 grams) by the molar mass to get the number of moles. In this case, 48 grams / 18 grams/mol ≈ 2.67 moles of water.
If you have 6.02 x 1023 molecules of H2O. What is the mass of this sample?
The molar mass of water (H2O) is approximately 18 g/mol. To find the mass of 6.02 x 10^23 molecules, you would divide by Avogadro's number (6.02 x 10^23) and then multiply by the molar mass of water. This would give you a mass of approximately 18 grams.
What is the mass of 7 mole of h2o?
To find the mass of 7 moles of water (H₂O), first note that the molar mass of water is approximately 18 grams per mole. Therefore, the mass of 7 moles of water can be calculated by multiplying the number of moles by the molar mass: 7 moles × 18 g/mol = 126 grams. Thus, the mass of 7 moles of H₂O is 126 grams.
How many grams are in 4 molecules of water?
The molar mass of water (H2O) is approximately 18 grams/mol. Therefore, for 4 molecules of water, the total mass would be 4 x 18 = 72 grams.
if I start with 5 grams of C3H8, what is my theoretical yield of water?
100 grams
What is 1 mol of H2O in grams?
in order to find the mass of H20 you need the molar mass which is 18.01g/mol and to calculate the mass you just multiply by the number of moles. 18.01 * .20 = 3.60g
What the molar mass of water?
The molar mass of water is 18 g/mol.
What is the molar mass of the following compound H2O?
The molar mass of hydrogen gas (H2) is 2.0158g. Hydrogen gas is diatomic therefore it's formula is H2. The atomic mass of hydrogen is 1.0079g and multiplying by the two hydrogen atoms is equal to 2.0158g.
