Answer:

The molecular weight of Ca_3(PO_4)_2 is 310.18 g/mol.

Explanation:

The molecular weight of Ca_3(PO_4)_2 :

Atomic mass of calcium = 40.08 g/mol

Atomic mass of phosphorous = 30.97 g/mol

Atomic mass of oxygen = 16.00 g/mol

Number of calcium atom = 3

Number of phosphorus atom =1 × 2

Number of oxygen atom =4 × 2 = 8

Molecular weight ofCa_3(PO_4)_2 = M

M=3\times 40.08 g/mol+2\times 30.97g/mol+8\times 16.00g/mol

M = 310.18 g/mol

What is the differnce between the atomic number and the mass number of an element?
MrRissso [65]
Atomic number refers to the number of protons within the nuclei of an element's atoms (and therefore the number of electrons) while mass number refers to the number of protons and neutrons within the nucleus.

If the pOH of a nitric acid (HNO3) solution is measured as 11, what is the concentration of HNO3 solution?
Illusion [34]

1 gram of HNO3 will be equal to 1/63.01 moles. Therefore, we can say that 1 liter of Nitric acid contains 15.6976 moles or in other words molarity of 70% (w/w) Nitric acid is equal to 15.6976 M.

Known values  

Molecular weight of HNO3 63.01 g/mole

Concentration of Nitric acid 70% (% by mass, wt/wt)

Calculate the osmotic pressure of a solution containing 24.6g of glycerin in 250ml of solution at 298K
gavmur [86]
The formula to calculate osmotic pressure is 
Osmotic Pressure = M R T
M = Molarity
R = Ideal Gas Constant
T = Temperature in Kelvin

So, 
24.6/.2254kg=109.139g /kg  >>>>> Molarity
109.139 x mols/92 g = 1.186 mols kg^-1
1.186 x 0.08134 x 298 K = 28.755 atm
<span>1.06852 x 0.08134 x 298K= 26.5 atm

The answer is 26.5</span>
