Answer:
60 mL
Explanation:
200 mL = 0.2 L
We know that:
Molarity = Moles / Liters
So:
4.20 M = moles / 0.2 L
moles = 4.20 x 0.2 = 0.84
Then:
14.0 M = 0.84 moles / Liters
Liters = 0.84 moles / 14.0 M = 0.06 L
Since they want the answer in mL, convert 0.06 to get 60 mL

The specific heat of the iron can is determined as 0.449 J/g⁰C.
<h3>Specific heat of the iron can</h3>
The specific heat of the iron can is calculated as follows;
Q = mcΔθ
c = Q/mΔθ
where;
- Q is quantity of heat
- Δθ is change in temperature
- m is mass
c = 256/(50 x 11.4)
c = 0.449 J/g⁰C
Thus, the specific heat of the iron can is determined as 0.449 J/g⁰C.

Answer:
202,020 pennies
Explanation:
The amount of pennies in 1 dollar is 100.
Basically, you just multiply the whole dollar amount (2020) by 100 and then add 20 to find the amount of pennies.
(2020)(100)+20= 202,000+20= 202,020 pennies.
