7 0

Answer:

Data:

Mass of solute: 45 g

m.mass of solute: 110 g/mol

volume of water: 1.5 L

Explanation:

percent w/v: 45/1500 *100

vol of solution: 3cm3=0.003dm3

M=g of solute/m.mass of solute*dm3 of sol

M= 45/110*0.003

M=14.85

How many neutrons are there in 9 molecules of P4 with mass number 31 and proton number 15?
aalyn [17]

A = mass number which is equal to the total number of protons + number of neutrons, Z= atomic number of any element which is also indicates Number of protons or number of electron in the given atom.


The formula to calculate neutron would be :

mass number - proton  

31   - 15     = 16

Thus 16 neutrons are found in one atom of P  

There are 4 atom in one molecule

Thus  

4 atom /1 molecule * 9 molecule * 16 neutron / 1 atom  

= 4*9*16= 576 neutrons
