2. Determine the molarity of the NaOH solution in each trial. a. Trial 1 Molarity: b. Trial 2 Molarity: 3. Calculate the average
butalik [34]

Answer:

This question is incomplete

Explanation:

This question is incomplete but...

1) You can calculate the molarity of the NaOH for each trial by following the steps below.

The formula for Molarity (M) is

M = number of moles (n) ÷ volume (V)

where the unit of volume must be in Litres or dm³

The unit of molarity is mol/dm³ or mol/L or molar conc (M)

The final answer must have the unit of molarity

If the number of moles is not provided, look out for the mass of NaOH used and then calculate your number of moles (n) as

n = mass of NaOH used ÷ molar mass of NaOH

Where the atomic mass of sodium (Na) is 23, oxygen (O) is 16 and hydrogen (H) is 1. Hence, molar mass for NaOH is 23 + 16 + 1 = 40 g/mol

n = mass of NaOH used ÷ 40

2) Average Molarity will be (Trial 1 Molarity +Trial 2 Molarity) ÷ 2

Answer must be in mol/dm³ or mol/L or M

3) Label the volumentric flask containing the NaOH solution with the answer gotten from (2) above

How would a disease that damages the nucleus most directly affect the functioning of cells?
RSB [31]

Answer:

Hereditary information in the cell would be destroyed.

Explanation:

The nucleus can be defined as a membrane bound organelle that is found in eukaryotic cells. The main function of the nucleus is that it controls all activities that is related to the growth of the cell and also reproduction. The nucleus contains the cell hereditary information(DNA).

The nucleus is the most important organelle in the cell, It can sometimes be referred to as the brain of the cell. Therefore any health related condition that affects the nucleus would directly destroy all hereditary information that is stored in the cell.
