WARRIOR [948]

Answer:

Formation volume factor  = 1.36

The solution gas-oil ratio = 0.00356

Explanation:

Given Data;

Volume of oil reservoir = 227.0 cc

Volume of oil in the tank = 167.4 cc

Separator production = 0.537 scf

Stock tank production = 0.059 scf

formation volume factor of the oil =?

The solution gas-oil ratio = ?

1. Formation volume factor is calculated using the formula;

Formation volume factor = volume of oil reservoir/volume of oil stock tank

Substituting, we have

Formation volume factor = 227.0/ 167.4

                                          = 1.36

2. The solution gas-oil ratio can be calculated using the formula;

The solution gas-oil ratio= total gas in scf/volume of stock tank

                                         = (0.537 + 0.059)/167.4

                                         = 0.596/167.4

                                        =0.00356

If 3.50 moles of sodium chloride is added to your food, how many grams is added?
Ksenya-84 [330]

Answer:

204.8g

Explanation:

The number of moles of a substance is related to its mass and molecular mass as follows:

mole (n) = mass (m) ÷ molar mass (MM)

According to this question, 3.50 moles of sodium chloride (NaCl) is added to a food.

Molar mass of NaCl = 23 + 35.5

= 58.5g/mol

Using mole = mass/molar mass

Mass = molar mass × mole

Mass = 58.5g/mol × 3.5mol

Mass = 204.75

Mass = 204.8grams.

Therefore, 204.8grams of NaCl or common salt was added to the food.
