What is the mass of 5 moles H2?
The molar mass of H2 is 2 g/mol. To find the mass of 5 moles of H2, you would multiply the molar mass by the number of moles: 2 g/mol * 5 mol = 10 grams.
What is number of the H atoms in 6.37ng of C6H5NO2?
The molar mass of C6H5NO2 is: C: 6 atoms x 12 g/mol = 72 g/mol H: 5 atoms x 1 g/mol = 5 g/mol N: 1 atom x 14 g/mol = 14 g/mol O: 2 atoms x 16 g/mol = 32 g/mol Total = 123 g/mol 6.37 ng is equivalent to 6.37 x 10^-9 g. Calculate the number of moles using the molar mass: 6.37 x 10^-9 g / 123 g/mol ≈ 5.17 x 10^-11 mol There are 5 H atoms in one molecule of C6H5NO2, so in 5.17 x 10^-11 mol, there are approximately 5.17 x 10^-11 mol x 5 = 2.59 x 10^-10 moles of H atoms.
What is the equivalent weight of boron?
Boron is a chemical with a symbol of B and an atomic number of 5. The equivalent weight of boron is dependent on the chemical that it is combining with.
A sample of gold has a mass of 5.00 x 10-3g. what amount of gold in atoms does the sample contain?
To determine the number of gold atoms in the sample, you can use the molar mass of gold (197 g/mol) to first find moles, then convert moles to atoms using Avogadro's number (6.022 x 10^23 atoms/mol). First, find moles: 5.00 x 10^-3 g ÷ 197 g/mol = 2.54 x 10^-5 mol. Then, convert moles to atoms: 2.54 x 10^-5 mol x 6.022 x 10^23 atoms/mol = 1.53 x 10^19 atoms.
How many moles are in 4.5 g of AgNO3?
To find the number of moles in 4.5 g of AgNO3, you first need to determine the molar mass of AgNO3 which is 169.87 g/mol. Then you can use the formula: moles = mass / molar mass. Therefore, moles = 4.5 g / 169.87 g/mol ≈ 0.0265 moles.

What is the answer to this problem If 1 plus 5 equals 12 and 2 plus 10 equals 24 and 3 plus 15 equals 36 then 5 plus 25 equals what?
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
