The final temperature of the mass of gold is  737 °C.

<h3>What is the specific heat capacity of gold?</h3>

The specific heat capacity of gold is 0.126 J/g/K

The final temperature, T2 of the gold is calculated as follows:

T2 = T + Q/mc

where;

T is initial temperature, m is mass, and c is specific heat capacity of gold.

T2 = 27 + 2.3 x 1000/(25 x 0.126)

T2 = 737 °C

Therefore, the mass and heat capacity of gold determines its final temperature.

In fractional distillation, liquid can be seen running from the bottom of the distillation column back into the distilling flask
shepuryov [24]

Answer:

substances with a higher boiling point are returning back to the flask which allows another substances with the specific context temperature (lower boiling point) to boil over and be purified.

Explanation:

The reason it happens because the lower boiling point substance vaporizes and crosses over while the other substance is waiting for its boiling point to reach

I have a brick, dimensions 4 cm tall, 9 cm wide, and 25 cm long, with a mass of 1250 g. What is the density?
Likurg_2 [28]

Answer:

1.389

Explanation:

P = m / V

m = 1250

V = 4x9x25 = 900

1250/900 = 1.388889

75.0 grams NaBr<br> Find the molar mass and number of moles
AVprozaik [17]

Answer:

Molar mass = 103.0 g/mol,

0.728 mol NaBr

Explanation:

Molar mass M(NaBr) = M(Na) + M(Br) = 23.0 + 80.0 = 103.0 g/mol

75.0 g NaBr * 1 mol NaBr/103.0 g NaBr=0.728 mol NaBr

How many moles of potassium nitrate are required to make 550 mL of a 2.1M solution?
stira [4]

Answer:

1.155 moles of potassium nitrate are required to make 550 mL of a 2.1M solution.

Explanation:

In a mixture, the chemical present in the greatest amount is called a solvent, while the other components are called solutes.

Molarity is a unit of concentration of a solution and indicates the amount of moles of solute that appear dissolved in each liter of the mixture. In other words, the Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a given volume.

The Molarity of a solution is determined by the following expression:

Molatity( M)=\frac{number of moles of solute}{Volume}

Molarity is expressed in units (\frac{moles}{liter}).

In this case:

  • Molarity= 2.1 M
  • number of moles of solute= ?
  • Volume= 550 mL= 0.550 L (being 1L=1000 mL)

Replacing:

2.1 M= 2.1 \frac{moles}{liter} =\frac{number of moles of solute}{0.550 liters}

Solving:

number of moles of solute= 2.1 M* 0.550 L

number of moles of solute= 1.155 moles

1.155 moles of potassium nitrate are required to make 550 mL of a 2.1M solution.
