How many moles are in 45 grams of potassium oxide?
45/94.2 is 0.4777 moles
If you have a material that has a volume of 45mL and a mass of 180 grams what is the density of the material?
The density of the material is its mass divided by its volume. In this case, the density would be 180 grams / 45 mL = 4 grams/mL.
How many moles are in 45g of F?
The molecular mass of fluorine gas, F2 is 2(19.0) = 38.0Amount of F2 = mass of sample/molar mass = 9.5/38.0 = 0.25mol There are 0.25 moles of fluorine in a 9.5g pure sample.
How many moles in 55g of lithium chloride?
To find the number of moles in 55g of lithium chloride, we first need to calculate the molar mass of lithium chloride, which is approximately 42.39 g/mol. Then, we divide the mass given (55g) by the molar mass to get moles. Therefore, 55g of lithium chloride is approximately 1.30 moles.
How many molecules are in 45 g of silver?
To determine the number of molecules in 45 g of silver, you first need to calculate the number of moles of silver using its molar mass (107.87 g/mol). Then, you can use Avogadro's number (6.022 x 10^23) to convert moles to molecules.
How many grams are in 2.50 moles of H2O?
To calculate the number of grams in 2.50 moles of H2O, you first need to know the molar mass of water (H2O), which is approximately 18.015 g/mol. Then, you can use the formula: grams = moles x molar mass. So, 2.50 moles of H2O is equivalent to 45.04 grams (2.50 moles x 18.015 g/mol).
How many moles are in 45 grams of potassium oxide?
45/94.2 is 0.4777 moles
How many atoms are in 45 grams of pb?
To find the number of atoms in 45 grams of Pb (lead), we need to first calculate the number of moles. The molar mass of Pb is approximately 207.2 g/mol. By dividing the given mass by the molar mass, we can find the number of moles. Then, we can convert moles to atoms using Avogadro's number (6.022 x 10^23 atoms/mol).
What is the mass in grams of 45 ml of water?
45mL of plain water has a mass of about 45 grams.

You have a rock with a volume of 15 cm3 and a mass of 45 g.?
45/15= 3 Where density is equal to mass over volume
If you have a material that has a volume of 45mL and a mass of 180 grams what is the density of the material?
The density of the material is its mass divided by its volume. In this case, the density would be 180 grams / 45 mL = 4 grams/mL.
