How many moles are contained in 1.23 grams of krypton?
# moles = mass / molar mass = 1.23g / 83.80g/mol =1.47x10^-2 moles There are 1.47x10^-2 moles in 1.23g of krypton
How many gmole of chromium II hydroxide?
So you have 2 moles of Chromium (Cr). Use equation moles=mass (in grams)/RMM. The bottom can be called Relative Molecular Mass (RMM), or Relative Atomic Mass (RAM) depending on the situation. Chances are you know it as Molar mass. You can call it that too. Using moles= mass (g)/RMM --> 2 moles = mass (g)/51.996 --> 2 x 51.996 = the mass in grams of Chromium --> 103.992g in 2 moles of Chromium.
What is the mass of 7.346 moles of CaOH2?
The mass of 7,346 moles of Ca(OH)2 is 544,3 g.
How many grams in 2 moles of sodium?
Mass of 2 moles of Na = 2 x atomic mass of Na = 2 x 23.0 = 46.0g
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
Calculate the number of moles in 112 g of iron?
Molar mass of iron is 56g. Given mass of iron= 112g No. of moles = Given mass/Molar Mass => 112g/56g= 2 moles
What is the mass of 2.00 moles of carbon dioxide CO2?
to work out the number of moles, you divide the mass by the relative atomic mass so 200 divided by 44 = 4.55 moles
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 hydrogen converted into moles?
The molar mass of hydrogen is 2 g.
What is the mass of 1.5E-2 moles of xenon tetra- fluoride?
mass (in grams) = number of moles x molecular weight. So for 0.015 moles of XeF4, the mass = 0.015 x 207.284 = 3.11 g
What is the reactant of the mass?
The mass of 2 moles of H2 gas = 2.00 x 2 = 4.00 g
How many atoms of sodium are present in Moles of sodium and what is the mass of it?
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
