Mass number represents the sum of the protons and the neutrons.

Mass number = # protons + # neutrons

So, since we are given the mass number and the number of protons, we can plug those in to find the number of neutrons.

33 = 15 + ?

How many grams of an 8% w/w progesterone gel must be mixed with 1.45 g of a 4% w/w progesterone gel to prepare a 5.5% w/w gel?
Nimfa-mama [501]

Answer: 0.87 g of an 8% w/w progesterone gel must be mixed with 1.45 g of a 4% w/w progesterone gel to prepare a 5.5% w/w gel.

Explanation:

According to the dilution law,

C_1w_1+C_2w_2=C_3w_3

where,

C_1 = concentration of ist progesterone gel = 8%w/w

w_1 = weight of ist progesterone gel  = x g

C_2 = concentration of another progesterone gel  = 4% w/w

w_2 = weight of another progesterone gel = 1.45 g

C_3 = concentration of resulting progesterone gel  = 5.5%w/w

w_3 = weight of resulting progesterone gel  = (x+1.45) g

8\times x+4\times 1.45=5.5\times (x+1.45)

x=0.87

Thus 0.87 g of an 8% w/w progesterone gel must be mixed with 1.45 g of a 4% w/w progesterone gel to prepare a 5.5% w/w gel.
