Answer:
How may we help kind sir
Explanation:
and if this was for points thanks
A Beta particles is emitted when an atom of 85Kr spontaneously decays.
0.05 * V1 = 250 * 10
<span> V1 = 2500 / 0.05 </span>
<span> V1 = 2500 * 20 </span>
<span> V1 = 50000 mL </span>
<span>V1 = 50 Liters .
Hope this helped! :3</span>
Answer:
The mass of silver is 
Explanation:
Given that,
The volume of the truck is 402 cubic feet or 1.138 x 10⁷ mm.
The density of silver is 10.49 g/mL.
We need to find the mass of silver that will fit in this moving truck. Density equals mass divided by volume. So,
1 gram = 10⁻⁶ Megagram
Hence, the mass of silver is
