What is the mass in grams of 5.25 x 1024 molecules of NaOH?
Colt1911 [192]

Answer: The mass is 348.8g

Explanation:

We begin by using Avogadro's number to convert the number of molecules of  Sodium Hydroxide to moles.

6.02 x 10∧23 molecules of NaOH -------> 1 mole of NaOH

∴ 5.25 x 10∧24 molecules of NaOH -------> 1/ 6.02 x 10∧23 x 5.25 x 10∧24 =

                                                                    8.72moles.

Having found the number of moles, we then move from moles to gram by using the molar mass of NaOH (i.e the mass of 1 mole of NaOH).

1 mole of NaOH is equivalent to 40g (Molar Mass)

8.72 moles of NaOH would be equivalent to; 40/ 1  x 8.72 = 348.8g

The mass in 5.25 x 10∧24molecules of NaOH is 348.8g

If 840. mL of linseed oil has a mass of 700. g, calculate the density of linseed oil.
aleksklad [387]

Density can be determined as:

d = m /V

whereas, m is mass of compound

v is volume

d = 700 /840 = 0.83 g /mL

Thus density is 0.83 g /mL

Which component of the dri reflects the requirement of a nutrient for 50 percent of healthy americans and canadians in a specifi
grandymaker [24]

The component of the dri reflects the requirement of a nutrient for 50 percent of healthy americans and canadians in a specific life stage and gender is Estimated Average Requirement (EAR).

What is EAR?

A daily food intake number known as the Estimated Average Requirement (EAR) is one that is thought to satisfy the needs of 50% of healthy persons in a given life stage and gender group.

Based on a review of the scientific literature, the estimated average requirements (EAR) are predicted to meet the needs of 50% of the population in that age range.

It serves as the foundation for the creation of RDAs and is employed to assess the sufficiency of nutritional consumption for a given population.
