If you are going 30 miles an hour in good condition, it will take how many feet to stop .

Answers

Answer:

158400 feet per hour

Explanation:

First we find:

How many feet are in miles per hour?

Multiply your speed in miles per hour by 5,280. This is the number of feet in a mile. The result is your speed in feet per hour.

For example, 30 miles per hour times 5,280 feet per mile is 158,400 feet per hour.

Determine the mass percent (to the hundredths place) of h in sodium bicarbonate (nahco3).

Answers

The mass percent of H in NaHCO₃ is 1.19%

We'll begin by calculating the molar mass of NaHCO₃. This can be obtained as follow:

Molar mass of NaHCO₃ = 23 + 1 + 12 + (16×3)

= 23 + 1 + 12 + 48

= 84 g/mol

From the molar mass of NaHCO₃, we can see that 1 g of H is present in 84 g of the compound (NaHCO₃)

Finally, we shall determine the mass percent of H in NaHCO₃. This can be obtained as follow:

Mass of H = 1 g

Mass of NaHCO₃ = 84 g

Mass percent of H =?

Mass percent = (mass of element )/(mass of compound ) X 100

Mass percent of H = (1)/(84) × 100

Mass percent of H = 1.19%

Therefore, the mass percent of H in NaHCO₃ is 1.19%

NaHCO3 = 84.0066 g/mol

H = 1.00794 g/mol

(1.00794 g/mol) / (84.0066 g/mol)

= 0.011998

= 1.20% H
