To convert from liters/second to cubic gallons/minute, multiply the number of liters/second by 15.850 0 0.0353 00.2642 0 60

ivanzaharov [21]

Answer: 15.850

Explanation:

The conversion used from liters to gallons is:

1 L = 0.264172 gallon

The conversion used from sec to min is:

60 sec = 1 min

1 sec = $\frac{1}{60}\times 1=0.017min$

We are asked: liters/sec = gallons/min

$liters/sec=\frac{0.264172}{0.017}=15.850gallons/min$

Therefore, to convert from liters/second to gallons/minute, multiply the number of liters/second by 15.850.

If the percent (mass/mass) for a solute is 8% and the mass of the solution is 200 g, what is the mass of solute in solution?

tatyana61 [14]

Answer:

The answer to your question is 16 g

Explanation:

Data

Percent by mass = 8%

Mass of the solution = 200 g

Mass of solute = ?

Formula

Percent by mass = mass of solute / mass of solution x 100

- Solve for mass of solute

Mass of solute = Percent by mass x mass of solution / 100

- Substitution

Mass of solute = 8 x 200 / 100

- Simplification

Mass of solute = 1600 / 100

- Result

Mass of solute = 16 g
