The formula for the molecular formula is molar mass/ empirical formula
So, the empirical formula of C3H7 is equal to C*3 + H*7 which is equal to 12*3 + 7. Then use the molecular formula = 86 / (12*3+7) = 2
Therefore, the molecular formula is 2 times the empirical formula which is C6H14.
The number of beats the person have in 1.7 years is 6.7 x 10⁷ beats.
<h3>
Number of beats of the person</h3>
The number of beats of the person is calculated as follows;
n = bt
where;
- b is the beat rate
- n is number of beats
- t is time or duration
b = 75 beats/min
t = 1.7 years = 893520 mins
n = 75 beats/min x 893520 mins
n = 67,014,000
n = 6.7 x 10⁷ beats
Thus, the number of beats the person have in 1.7 years is 6.7 x 10⁷ beats.
