Answer:
139.5 mL.
Explanation:
To solve this question we will be making use of dilution law which is given by the equation below;
C1 × V1 = C2 × V2. Where C1 = the initial concentration, V1 = Initial volume, C2 = final concentration, V2 = Initial volume.
So, from the question we are given the following parameters; V1 = 186 mL, C1 = 0.275 M, C2 = 1.10 M and V2 = unknown (??).
Therefore, slotting in the above parameters into the dilution equation we have;
0.275 × 186= 1.10 × V2.
V2 = 0.275 × 186/ 1.10.
V2 = 46.5 mL.
The volume of solvent that has evaporated from the 0.275 M solution = 186 mL - 46.5 mL= 139.5 mL.
Given:
Molar mass of CO2 = 44.01g/mol
3.21x10^25 molecules of CO2
Required:
Mass of CO2
Solution:
Avogadro’s number states that
for every mole of atom, there are 6.023x10^23 units of atom. The units may be
formula units, atoms. In here, you need to divide 3.21x10^25 molecules of CO2
to 6.023x10^23 molecules per mole.
3.21x10^25 molecules of CO2 / 6.023x10^23
molecules per mole = 53.30 moles CO2
53.30 moles CO2 (44.01g/mol CO2)
= 2346 g of CO2
The answer would be absorbed
Answer:
The answer is
<h3>6000 N/m² or 6000 Pa</h3>
Explanation:
The pressure exerted by an object given the force of the object and the area can be found by using the formula
where
P is the pressure
f is the force
a is the area
From the question
f = 2400 N
a = 0.4 m²
So we have
We have the final answer as
<h3>6000 N/m² or 6000 Pa</h3>
Hope this helps you
Answer:
A. the bond's yield to maturity is equal to its coupon rate.
Explanation:
The coupon rate is that amount of bond measured on the loan amount whereas the maturity yield is the rate held up to the settlement date and the investment arise up to the maturity date.
Since the bond is currently trading at its face value that means the bond price is equal to the face or par value
So, the appropriate option is A.
