We can calculate years by using the half-life equation. It is expressed as:
A = Ao e^-kt
<span>where A is the amount left at t years, Ao is the initial concentration, and k is a constant.
</span>From the half-life data, we can calculate for k.
1/2(Ao) = Ao e^-k(1620)
<span>k = 4.28 x 10^-4
</span>
0.125 = 1 e^-<span>4.28 x 10^-4 (</span>t)
t = 4259 years
Answer: he gave him a map of somewhere
Explanation:
The compound responsible for the characteristic smell of garlic is allicin, that is having molecular formula C₆H₁₀OS₂.
Molar mass of C₆H₁₀OS₂=162.26 g mol⁻¹.
number of moles of C₆H₁₀OS₂=1 mol
So mass of C₆H₁₀OS₂ can be calculated as:
Given mass of the C₆H₁₀OS₂= 162 g
4 Hydrogen Atoms should be correct. Because the 4 infront of it signifies the amount of hydrogen. It would also be 4 hydrogen atoms if it were written as H4N3, because the 4 is still around the H (as long as the 4 is under scored)
