<span>We look at the end of the day:
n(HNO3) added = 0.500*17.0/1000 = 0.00850 mol
n(NH3) = 0.200*75.0/1000 - 0.00850 = 0.00650 mol
[NH3] left = 0.00650*1000/(17.0+75.0) = 0.070652
M [OH-] = Kb * [NH3] = 0.070652*1.8*10^(-5) = 1.27174 x 10^(-6)
pOH = -log[OH-] ≈ 5.8956 pH = 14 - pOH ≈ 8.10</span>
Answer:
18,01528
Explanation:
So we know that the equation for density is:

where D is the density, m is the mass in grams, and V is the volume in mL.
So since we know two of the variables, mass and density, we can solve for the volume:



Therefore, the volume of this urine sample is 144.12mL.
Answer:
Always equal to the total moles of the products.
Explanation:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction equal to the mass of the reactants.
A uniform cube is subjected to volume expansion. Each side gets decreased by 1%, then the bulk strain is 0.03.
<h3>What is Volume?</h3>
Volume is the space occupied by a three-dimensional object.
<h3 />
Given that, the side cube is l, then
volume V = l³

For change in volume
% Change in volume = 3× % change in length
= 3 × 1%
Hence, bulk strain = 0.03.
Thus, the bulk strain is 0.03.
