It takes 53.0 J to raise the temperature of an 11.0 g piece of unknown metal from 13.0∘C to 24.2 ∘

You need to use q = mc(delta t)
Solve for c: 

c = q / m(delta t) 

q = 55.o J 
m = 11.0 g 
delta t = 24.5 - 13.0 = 11.5 deg C 

c = 55 J / 11.0 g)(11.5 C) 
c = 0.435 J/ g C

Which unit conversion allows you to convert 21.0 gallons into milliliters?

Romashka-Z-Leto [24]

79470.2mL

Explanation:

Given:

Volume = 21gallons

problem, convert to milliliters;

gallons to milliliters

1 liter = 1.057 quarts

1 gallon = 4 quarts

we can simply solve this by establishing and using a conversion factor of 1 ;

1 gallon = 4 quarts

1.057 quarts = 1 liter

0.001L = 1mL

21gallons x $\frac{4qt}{1gal} x \frac{1 liter}{1.057qt} x \frac{1mL }{0.001L}$ = 79470.2mL

we say;

From; $\frac{4qt}{1gal} x \frac{1 liter}{1.057qt} x \frac{1mL }{0.001L}$

1gallon = 3784.2mL
