How many moles of Na2SO4 can be made with 7.28 mol of H2SO4?
Slav-nsk [51]

Answer:

7.28 mol Na2SO4

Explanation:

Since it is already in moles, all we have to do is use a molar ratio

A molar ratio is the proportions of reactants and products using the balanced equation. When writing a mole ratio, the given information must cross out with the right thing.

7.28 mol H2SO4 * 1 mol Na2SO4/1 H2SO4 = 7.28 mol Na2SO4

Vedmedyk [2.9K]

Answer:

In 4 years the carbon monoxide level reach 7.8 parts per million.

Explanation:

The average daily level of carbon monoxide in the air is given by :

c(x) = 0.5x + 2 parts per million..[1]

The population of the region after t years is modeled by the formula :

x(t) = 10 + 0.1t^2...[2]

If level of carbon monoxide level reach 7.8 parts per million in t years.

Using [1] to calculate value of x.

c(x)= 7.8 parts per million

c(x) = 0.5x + 2  parts per million

7.8 parts per million = (0.5x + 2 ) parts per million

Solving for x , we get ;

x = 11.6

Using [2] to calculate value of t.:

x(t) = 11.6

11.6 = 10 + 0.1t^2

Solving for 't' we get ;

t = 4 years

In 4 years the carbon monoxide level reach 7.8 parts per million.
