Remember moles = mass(g) / Mr
The 'Mr' is the relative molecular mass.
The Mr(Baking soda ; sodium hydrogen carbonate ; NaHCO3) is
Na x 1 = 23 x 1 = 23
H x 1 = 1 x 1 = 1
C x 1 = 12 x 1 = 12
O x 3 = 16 x 3 = 48
23 + 1 + 12 + 48 = 84 ( Mr of NaHCO3)
Hence
mol(NaHCO3) = 2.00g / THe answers!!!!!

∙ 15y agoFor this you need the atomic (molecular) mass of NaHCO3. Take the number of grams and divide it by the Atomic Mass. Multiply by one mole for units to cancel. NaHCO3=84.0 grams
2.00 grams NaHCO3 / (84.0 grams) = .0238 moles NaHCO3

How many moles of sucrose are in 200 grams?
200g times 342.2965 g/mol = 68459.3 moles
What is the mass of 200 moles of Fe?
200 (mol) * 56.0 (g/mol) = 11,200.0 grams
How many moles of CH4 are in 200 grams of CH4?
200 g CH4 x 1 mole CH4/16 g = 12.5 moles CH4
How do you convert 200mL to moles?
1 mole of NaCl is 58.44 g 200 g NaCl * (1 mol NaCl/58.44 g NaCl) = 3.422 mol NaCl There are about 3.4 moles in 200 grams of NaCl.
How many moles is 3 grams of carbon?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Carbon's atomic mass is 12.011 grams.

What is the number of moles of 200g of Fe?
For this you need the atomic (molecular) mass of FeCl3. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. FeCl3=162.4 grams .200 moles FeCl3
How many moles of CH4 are in 200 grams of CH4?
200 g CH4 x 1 mole CH4/16 g = 12.5 moles CH4
How many moles are in 1200 grams of calcium bromide?
The molecular weight of Calcium Bromide is extremely close to 200. So 1200/200 = 6 moles present.

Can you use baking powder instead of baking soda in peanut butter bar cookies?
Hmmm. One can not substitute flour with baking powder. One can however substitute selfraising flour with ordinary flour and a few teaspoons of baking powder. (My best guess would be approx 1 teaspoon of baking powder per 150-200 grams of flour.)
What is the molarity of 200 ml of solution which 2.0 moles of sodium bromide is dissolved?
So molarity means moles per litre. but you don't have a litre. if you did you'd have 1000/200 times the moles that you have. 2 moles / 200 x 1000 is 10 moles. As it is per litre, it is 2 molar.
