If ine mole of pennies were divided amung 250 million peoplein
Airida [17]

Answer:

2.4088\times 10^{13} dollars each person will receive.

Explanation:

Number of people in which 1 mole of pennies is distributed = 250 million =

1 million = 10^6

250 million = 2.5\times 10^8 persons

Number of pennies in 1 mole = 6.022\times 10^{23}

Pennies per person:

\frac{6.022\times 10^{23} pennies}{2.5\times 10^8 persons}=2.4088\times 10^{15} pennies/person

1 penny = 0.01 $

2.4088\times 10^{15} pennies/person=2.4088\times 10^{15}\times 0.01 \$/person=2.4088\times 10^{13} \$/person

2.4088\times 10^{13} dollars each person will receive.

It is stuck on 0 ∘C during the entire melting or freezing process. None except melting is when you heat up and freezing when you cool down.</h3>
