To get the weight of the body fat, you multiply the percentage of body fat (as a decimal) by the total body fat:
133x0.115=19.95
The athlete's body contains 19.95 pounds of fat.
Molecules made up of two or more elements are called compounds. Water, calcium oxide, and glucose are molecules that compound.
Answer:
by using ideal gas law
Explanation:
ideal gas law:
PV=nRT
where:
P is pressure measured in Pascal (pa)
V is volume measured in letters (L)
n is number of moles
R is ideal gas constant
T is temperature measured in Kelvin (K)
by applying the given:
P(initial) V(initial)=nRT(initial)
P(final) V(final)=nRT(final)
nR is constant in both equations since same gas
then,
P(initial) V(initial) / T(initial) = P(final) V(final) / T(final)
then by crossing multiply both equations
V (final)= { (P(initial) V(initial) / T(initial)) T(final) } /P (final)
P(initial)=P(final)= 1 atm = 101325 pa
V(initial)= 6 L
T(initial) = 28°c = 28+273 kelvin
T(final) = 39°c = 39+273 kelvin
by substitution
V(final) = 6.21926 L
Hello.
The answer is that these properties are brittle, solid at room temperature, and have a high melting point.
Answer:
16.566g
Explanation:
The 0.223M barium bromide means there are 0.223 moles of barium bromide is 1000ml of barium bromide solution.
Now, we firstly need to know the number of moles in 250ml
And that is = (0.223 * 250)/1000 = 0.05575 mole
Now we need to know the amount in g of barium bromide to add.
From the relation : mass = number of moles * molar mass.
The molar mass of barium bromide is 297.14g/mol
mass = 297.14 * 0.05575 = 16.566g
