La nina tends to lead to drier, warmer weather in the southern united states, which causes drought in texas. which of these is likely to occur in texas during el nino? a. record high temperatures b. a record number of wildfires c. above average rainfall d. a decreased chance of flooding

(Your answer should be C. Above average rainfall)

but for the opposite of that question its:

A. More freezes

B. Drought

C. More rain

D. Flooding

The answer is B. Drought

1.85M

Explanation:

Sodium hydroxide has a chemical formula of NaOH

Given that,

Amount of moles of NaOH (n) = ?

Mass of NaOH in grams = 63g

For molar mass of NaOH, use the molar masses:

Sodium, Na = 23g;

Oxygen, O = 16g;

Hydrogen, H = 1g

NaOH = (23g + 16g + 1g)

= 40g/mol

Since, amount of moles = mass in grams / molar mass

n = 63g / 40.0g/mol

n = 1.575 mole

Volume of NaOH solution (v) = 850mL

[Convert 850mL to liters

If 1000mL = 1L

850mL = 850/1000 = 0.85L]

Concentration of NaOH solution (c) = ?

Since concentration (c) is obtained by dividing the amount of solute dissolved by the volume of solvent, hence

c = n / v

c = 1.575 mole / 0.85L

c = 1.85M [1.85M is the concentration in moles per litres which is also known as molarity]

Thus, the molarity of the solution is 1.85M
