1st you must find the molar mass of CaBr2.
Ca 40.08g * (number of moles in the compound) 1
Br 79.90g * 2
This give you the amount (g) in 1 mole of CaBr2.
Multiply by 14 and you get the answer.

How many moles of Ba(OH)2 are in 2400 grams of Ba(OH)2?
The answer is 14 moles.
The formula potassium dichromate is K2Cr2O7. How many grams of oxygen will be in 2 moles of potassium dichromate?
In one mole of potassium dichromate, there seven moles of oxygen. This means in two moles of K2Cr2O7, there are 14 moles of O, or 7 Moles of O2, which equals 224 grams.
How many grams of NH3 are produced when 10.0g of H2 reacts with excess N2?
Step 1: balanced equation for the synthesis of ammonia:N2 + 3H2 --> 2NH3Step 2: convert 10g H2 to moles:H2=2 g/mol; 10g = 5 moles of hydrogen.Step 3: use molar ratios (coefficients) in balanced equation to determine moles of product:3/2=5/x; solve for x to get 3.3 moles of ammonia (product).Step 4: use relationship between moles and grams to get grams of product:NH3=14+1+1+1=17 g/mol. Given 3.3 moles, 17(3.3)=56.1 grams NH3.
Calculate mass in grams of 2.110 moles of NH3?
You can find the mass of one mole of each of the individual elements by looking at the mass numbers.So, 1 mole of:N=14gH=1gsince there are 3 H's the total mass of 1 mole NH3 is 14+3=17gYou then multiply the actual number of moles by the g's per mole:=> 17x2.11=35.87g
How many grams are there in 3.3 x 1023 molecules of N2I6?
divide the amount of particles given in the question by avagado's number to get the amount in moles. 3.01 x 1023 / 6.022 x 1023 which is about 0.5 moles. them multiply the amount of moles by the mass of Nitrogen to get it in grams. 0.5 x 14 = 7g
How many moles of nitrogen gas are there in 35.7 gm of nitrogen gas?
molar weight of N = 14 grams/mole 35.7 grams/14 grams/mole = 2.55 moles
How many moles of nitrogen are there in 29 grams of nitrogen?
There are 29/14, or just over 2 moles of nitrogen in 19 grams.
How many moles of Ba(OH)2 are in 2400 grams of Ba(OH)2?
The answer is 14 moles.
How many moles of nitrogen in 42 grams of nitrogen?
As a rule of thumb, the atomic mass of an element equals the number of grams of that element equals a mole. Since the atomic mass of Nitrogen is 14, there are 14 grams in one mole of Nitrogen. Next, we just have to divide 42 by 14 and we get our answer: There are 2.9988 moles in 42 grams of Nitrogen.
The formula potassium dichromate is K2Cr2O7. How many grams of oxygen will be in 2 moles of potassium dichromate?
In one mole of potassium dichromate, there seven moles of oxygen. This means in two moles of K2Cr2O7, there are 14 moles of O, or 7 Moles of O2, which equals 224 grams.
How do you convert micron to grams per metre square?
14 grams per micron
How many moles are in 454 grams in sodium?
atomic waight of hydrogen = 1.0079 weight of one mole of hydrogen = its atomic mass in grams(just like all elements). therefore 454g/1.0079g = 450.4 moles of hydrogen.
How many moles are in 1200 grams of ammonia?
mol = mass/ Mr Mr = 14 + 3 = 17 mol = 1200/17 moles = 70.59
He formula for potassium dichromate is KËÃCrËÃOËÈ How many grams of oxygen will be in 2 moles of potassium dichromate?
224 grams of Oxygen will be in 2 moles of Potassium dichromate.
How can you convert 14 centimeters into grams?
multiply it by 564 and divide it by 34
