The final temperature : 44.5 °C
<h3>Further explanation</h3>
Heat can be formulated :
Q = m . c .Δt
Q = heat, J
m = mass, g
c = specific heat, J/gC
Δt= temperature
m= 625 g
Q=7.96 x 10⁴ J
c = 4.18 j/gC
t₁=75 C
C it is C because a geno type is the genetic material that predicts what that feature will look like. A phenotype is how that genotype made you look on the outside.

Answer:
c.boron-11
Explanation:
The atomic mass of boron is 10.81 u.
And 10.81 u is a lot closer to 11u than it is to 10u, so there must be more of boron-11.
To convince you fully, we can also do a simple calculation to find the exact proportion of boron-11 using the following formula:
(10u)(x)+(11u)(1−x)100%=10.81u
Where u is the unit for atomic mass and x is the proportion of boron-10 out of the total boron abundance which is 100%.
Solving for x we get:
11u−ux=10.81u
0.19u=ux
x=0.19
1−x=0.81
And thus the abundance of boron-11 is roughly 81%.
