Question

a solution of trioxonitrate (v) acid contained 0.67g in 100cm³. 31cm³ of this solution neutralized 25cm³ of a sodium trioxocarbonate(iv) solution. Calculate the concentration of the trioxocarbonate (iv) solution​

Answer 1

Answer:

0.67 / 100 : 31^3 : 31^3 / 25cm^3

x 10

0.67 / 100 = 67 / 10000000  grams/cm  :  29791 / 15625 / 29791    

149253.731  : 0.52

divide by 1000

= 149.253731

= 149.3 kg

Ratio kg = 149.3 : 0.5

Step-by-step explanation:

Mole Ratio

The mole ratio compares the number of moles in a balanced equation.

This is the comparison between the coefficients in front of the chemical formulas.

If a formula lacks a coefficient, it is the same as saying there is 1 mole of that species.

Mole ratios are used to predict how much product a reaction forms or to determine how much reactant is needed to make a set amount of product.

Mole Ratio Units

Mole ratio units are either mole:mole or else it is a dimensionless number because the units cancel out. For example, it's fine to say a ratio of 3 moles of O2 to 1 mole of H2 is 3:1 or 3 mol O2: 1 mol H2.
