Density of gasoline is 0.737 g/mL and volume of tank is 13.0 gal.
Since, 1 US gal=3.78 L
Volume of tank in L will be:
Also, 1 L=1000 mL
Thus,
Mass of gasoline can be calculated as follows:
m=d×V
Here, d is density and V is volume thus,
Therefore, mass of gasoline will be 
.
Answer:
Even small amounts of radiation over a prolonged period of time can be dangerous.
Explanation:
We all get exposed to radiation, such as through x-rays, and it's fine as one off experiences. However, if you're constantly dealing with radiation without any sort of protection, no matter how small the amount is, it could potentially lead to consequences like cancer. This is due to the fact that radiation can alter our genes
.50 M KCl because 5% is the same as .05, which makes the .50M more concentrated.
Answer:
a) Molarity = 0.199M
b) 21.6L of solution
c) 0.199 moles of sucrose in 1L
Explanation:
a) Molarity is the ratio of moles of solute (sucrose) in volume of solution (3.30L):
<em>Moles sucrose -Molar mass: 342,3g/mol-:</em>
225.0g * (1mol / 342,2965g) = 0.6573 moles
Molarity = 0.6573 moles / 3.30L
<h3>Molarity = 0.199M</h3><h3 />
b) 0.199M means 0.199 moles in 1L. 4.30 moles are in:
4.30 mol * (1L / 0.199mol) = 21.6L of solution
c) By definition, there are 0.199 moles of sucrose in 1L. This is the meaning of 0.199M
