The Answer is A CH2O

The molecular formula for glucose is C6H12O6. The subscripts represent a multiple of an empirical formula. To determine the empirical formula, divide the subscripts by the GCF of 6 which gives CH2O.

You want to make 100 mL of a 2.5 M stock solution of calcium chloride (molecular weight 110.98 g/mol). How many grams of calcium

Evgesh-ka [11]

Answer:

27.7 g

Explanation:

100 mL = 0.100 L

To solve this problem we use the definition of molarity:

M = mol / L

From the problem we're given M = 2.5 M and volume = 0.100 L. We use the above formula and calculate the required moles of calcium chloride (CaCl₂):

2.5 M = moles / 0.100 L

moles = 0.25 moles CaCl₂

Finally we use the molecular weight of calcium chloride to calculate the required mass:

0.25 moles CaCl₂ * 110.98 g/mol = 27.745 g CaCl₂

Rounding to the nearest tenth of a gram the answer is 27.7 g.

Find the volume of a gas at standard pressure if its volume at 780 mm Hg is 80 ml

Olin [163]

Answer:

0.082L or 82mL

Explanation:

Given parameters:

Pressure of gas = 780mmHg;

760mmHg = 1atm

780mmHg = $\frac{780}{760}$ = 1.03atm

Volume of gas = 80ml = 0.08L

Standard pressure = 1atm

Unknown:

Volume of gas = ?

Solution:

To solve this problem, we apply Boyle's law which states that "the volume of a fixed mass of gas is inversely proportional to the pressure if the temperature is constant".

Mathematically;

P₁ V₁ = P₂ V₂

P and V are temperature values

1 and 2 are initial and final states;

Insert the parameters and solve;

1.03 x 0.08 = 1 x V₂

V₂ = 0.082L or 82mL
