Answer:
Explanation:
Hello!
In this case, since the by-mass percent of a solution is a measure of the mass of the solute over the mass of the solution:
As we know the mass of the solution and the by-mass percent, we can compute the mass of glucose in the 480 g of solution:
Thus, by plugging in the data, we obtain:
Finally, since the solution is made up of glucose and water, we compute the mass of water as follows:
Best regards!
Answer:
A.
as the sum of the energy of the products and the energy of the reactants.
Explanation:
Because the sun is on top of the energy.
Answer:
Explanation:
since the substance is slippery , bitter and do not react with metal the substance can be a base. the ph of the substance will be greater than 7
Boyle's Law: P₁V₁ = P₂V₂
So (25 kpa)(0.21) = (2.5 kpa) V₂
(25 kpa × 0.21)/ 2.5 kpa = 2.1
2.1 = V₂
To determine this all you would need to do is rearrange the equation for density and solve for the value of volume. Then plug in the numerical values into the equation and solve for v.
D = m/v
Dv = m
V = m/D
V = 15.7 g/2.50 g/cm^3.
V = 6.28 ml.
