Question

1. find the measurements below in the form a x 10^n, where 1 ≤ a ≥ 10 is an integer. a) the density of air at 27°C and 1 atm pressure, 0.00161g / cm^3. b) the radius of a calcium atom, 0.000000000197m. I don't know where to even start??

Answer 1

A)

$\begin{gathered} 0.00161g=1.61\times10^{-3}g \\ \end{gathered}$

B)

$0.000000000197m=1.97\times10^{-10}m$
