What is the mass of 7.346 moles of CaOH2?
The mass of 7,346 moles of Ca(OH)2 is 544,3 g.
What is the mass of 2 moles of water (H2O)?
A mole of HNO3 weighs 63g (1 + 14 +16x3). Therefore, two moles weigh, 2 x 63 =126 g
How many moles of hydrigen are present in a 2 grams sample of hydrogen gas?
Mass (g) = Mr * Moles If you rearrange it, you get Moles = Mass/Mr Working with a 2dp periodic table you get: Moles = 2/1.01 =1.98 There are 1.98 moles of hydrogen in 2g of H2 gas.
What is the mass of 4.35x10-2 moles of zinc chloride ZnCl2?
To find the mass of 4.35x10^-2 moles of zinc chloride (ZnCl2), you need to multiply the number of moles by the molar mass of ZnCl2. The molar mass of ZnCl2 is 136.3 g/mol. Therefore, the mass of 4.35x10^-2 moles of ZnCl2 would be 5.93 grams.
How many grams is 2 moles of Iodine equal to?
mol = mass/Mr rearrange mol x Mr = mass 2 x 126.9g = 253.8g
What is the mass of 1.5E-2 moles of xenon tetra- fluoride?
To find the mass of 1.5E-2 moles of xenon tetrafluoride (XeF4), you would multiply the number of moles by the molar mass of XeF4. The molar mass of XeF4 is approximately 207.29 g/mol. Therefore, the mass of 1.5E-2 moles of XeF4 would be approximately 3.11 grams.
How many moles are in 2 grams of HCL?
To find the number of moles in 2 grams of HCl, you need to divide the mass by the molar mass of HCl. The molar mass of HCl is approximately 36.46 g/mol. Therefore, 2 grams of HCl is equal to 2/36.46 = 0.055 moles.
How many gmole of chromium II hydroxide?
To calculate the number of grams-moles (gmole) of chromium(II) hydroxide, you need to know the mass of chromium(II) hydroxide in grams and its molar mass. Once you have these values, you can use the formula: gmole = mass (in grams) / molar mass.
How many moles are in 16.4 g of Ca(NO3)2?
To find the number of moles in 16.4 g of calcium nitrate, Ca(NO3)2, you first need to calculate its molar mass. The molar mass of Ca(NO3)2 is approximately 164.1 g/mol. Using the formula for moles (moles = mass / molar mass), you can calculate the moles: ( \text{moles} = \frac{16.4 , \text{g}}{164.1 , \text{g/mol}} \approx 0.100 , \text{moles} ). Therefore, there are about 0.100 moles of Ca(NO3)2 in 16.4 g.
How many moles are there in 160g of bromine molecules?
To find the number of moles in 160g of bromine molecules, we first need to determine the molar mass of bromine which is approximately 79.9 g/mol. Then, we can use the formula: moles = mass / molar mass. Therefore, moles = 160g / 79.9 g/mol ≈ 2 moles.
How many moles are in 92g of ethanol?
To find the number of moles in 92g of ethanol, we first need to know the molar mass of ethanol, which is approximately 46g/mol. Then, we divide the given mass by the molar mass to get the number of moles. So, 92g of ethanol is equal to 2 moles.
What is the mass of hydrogen converted into moles?
The molar mass of hydrogen is 2 g.
