How many grams of NaCl is present in .75 L of a 1 M solution of NaCl?
finlep [7]

Answer:

The answer to your question is 43.9 g of NaCl

Explanation:

Data

Grams of NaCl = ?

Volume = 0.75 L

Molarity = 1 M

Number of moles = ?

Formula

Molarity = \frac{number of moles}{volume}

Solve for number of moles

Number of moles = Molarity x volume

Substitution

Number of moles = 1 x 0.75

                             = 0.75

Molecular weight of NaCl = 23 + 35.5 = 58.5

Calculate the grams of NaCl using proportions

                           58.5 g of NaCl ---------------- 1 mol

                              x                     ---------------- 0.75 moles

                              x = (0.75 x 58.5) / 1

                              x = 43.9 g of NaCl

100 grams of iron ore contains 30.06% oxygen find the empirical formula​
Serga [27]

Answer: Fe2O3

Explanation:

100 grams of iron ore = 30.06% oxygen

100 - 30.06 = 69.94% iron

Mr of Iron = 55.85

Mr of Oxygen = 16

Iron = 69.94/55.85 = 1.252

Oxygen = 30.06/16 = 1.879

1.879 / 1.252 = 1.5 of Oxygen

1.252/1.252 = 1 of Iron

we can write that as Fe1O1.5 but we can't use decimals therefore we have to multiply the whole thing by 2

So it comes out to be Fe2O3
