I believe that it is petroleum ether.
Answer:
1.3x10⁻⁸ mol/L
Explanation:
<em>0.0013μmol, Calculate concentration in mol/L</em>
<em />
To obtain concentration in mol/L we need to convert the μmoles to moles and mL to liters:
<em>Moles silver(II) oxide:</em>
0.0013μmol × (1mol / 1x10⁶μmol) = 1.3x10⁻⁹ moles
<em>Liters solution:</em>
100mL * (1L / 1000mL) = 0.1L
That means concentration in mol/L is:
1.3x10⁻⁹ moles / 0.1L =
<h3>1.3x10⁻⁸ mol/L</h3>
Less than the revolution perilous around earth
Answer: A 15 kg cart being pushed with a 200 N force.
