Scientists measure the volume of a liquid in which units of measure?

When 4.15 grams of silver nitrate is reacted with 1.11 grams of iron(III) chloride, which best represents the amount of silver c

PolarNik [594]

Answer:

The mass of silver chloride produced = 2.202 g

Explanation:

Equation of the reaction is given below

3AgNO₃(aq) + FeCl₃(aq) ----> 3AgCl(s) + Fe(NO₃)₃(aq)

molar mass of AgNO₃ = 170 g/mol

molar mass of FeCl₃ = 233.5 g/mol

molar mass of AgCl = 143.5 g/mol

3 moles of silver nitrate reacts with 1 mole of iron (iii) chloride to give 3 moles of silver nitrate

4.15 grams of AgNO₃ = 4.15/170 = 0.0244 moles of AgNO₃

1.11 grams of FeCl₃ = 1.11/233.5 = 0.0047 moles of FeCl₃

mole ratio of AgNO₃ to FeCl₃ = 0.0244/0.0047 = 5 : 1

therefore, FeCl₃ is the limiting reactant

0.0047 moles of FeCl₃ reacting will produce 0.0047 * 3 moles of AgCl = 0.0141 moles of AgCl

0.0141 moles of AgCl = 0.0141 * 143.5 g of AgCl = 2.02 g of AgCl =

Therefore mass of silver chloride produced = 2.202 g

Find the mass of each of these substances? 2.40 mol NaOH

damaskus [11]

Na = 23 x 2.40 = 55.2
O = 16 x 2.40 = 38.4
H = 1 x 2.40 = 2.40

55.2 + 38.4 + 2.4 = 96

2.40 mol of NaOH = 96 amu

The downward pressure on the hg in barometer is ______ the pressure of the atmosphere.

enyata [817]

The downward pressure on the hg in barometer is <u>the same as</u> the pressure of the atmosphere.

The atmospheric pressure or barometric pressure is the force exerted by the air in the atmosphere on the earth's surface.

The atmospheric pressure is caused by air molecules colliding with the surface. The atmospheric pressure at sea level is about 101 kPa and at the cruising altitude of a passenger plane it is 27 kPa.

The atmospheric pressure decrease as the height of a surface above ground level increases.

<h3>What is a barometer?</h3>

A barometer is a measuring instrument used to measure the atmospheric pressure or weight of the air, which is useful for making weather predictions.

How many moles of gold are there in 3.73 x 10^24 atoms of gold?

BARSIC [14]

Answer:

6.2moles of Gold

Explanation:

To solve this problem, we are going to use the mole concept approach.

Given that;

Number of atoms of gold is 3.73 x 10²⁴ atoms

Now;

In 1 mole of any substance, we have 6.02 x 10²³ atoms;

So;

If there 6.02 x 10²³ atoms in 1 mole of any substance;

3.73 x 10²⁴ atoms will contain $\frac{3.73 x 10^{24} }{6.02 x 10^{23} }$ = 6.2moles of Gold
