a solution of trioxonitrate (v) acid contained 0.67g in 100cm³. 31cm³ of this solution neutralized 25cm³ of a sodium trioxocarbo

FinnZ [79.3K]

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.

Stan lawn mower had 1/8 of a gallon of gasoline in the tank. Stan started mowing and used all of the gasoline. He put 6/10 of a

tigry1 [53]

Answer: Stan used $\frac{1}{24}\ gallon$ of gasoline.

Step-by-step explanation:

Given: The amount of gasoline in the tank of Stan lawn mower= $\frac{1}{8}\ of\ gallon$

Then he put the amount of gasoline in the tank= $\frac{1}{6}\ of\ gallon$

The total amount of gasoline filled in the tank = $\frac{1}{8}+\frac{1}{6}\ gallons$

⇒ The total amount of gasoline filled in the tank = $\frac{3+4}{24}=\frac{7}{24}\ gallons$

The amount of gasoline left in the tank after mowing= $\frac{1}{4}\ of\ gallon$

Now, the total gasoline used by Stan= $\frac{7}{24}-\frac{1}{4}=\frac{7-6}{24}=\frac{1}{24}\ gallon$

The money multiplier is critical in macroeconomics because it determines the cash supply, which affects interest charges. it is also critical in banking because it impacts economic coverage and the steadiness of the banking region.
