Answer:

Hg(NO₃)₂(aq) + Na₂SO₄(aq) → 2NaNO₃(aq) + HgSO₄(s)

Moles of Hg(NO₃)₂ = 55.42 / 324.7 ==> 0.1707 moles

Moles of Na₂SO₄ = 16.642 / 142.04 ==> 0.1172 moles

Limiting reagent is Na₂SO₄ as it controls product formation

Moles of HgSO₄ formed = 0.1172 moles

= 0.1172 x 296.65

= 34.757g

A cylinder with a mass of 98 grams is made of copper (density 8.94 g/cm³). If the radius of the cylinder is 2.0 cm, what is the

sasho [114]

The height of the described cylinder is 0.85 cm

Mass= 98g

Density= 8.9g/cm^3

Density= (mass/volume)

Substitute the values

8.94= 98/ volume

Volume= $\frac{98}{8.94}$

Volume= 10.97 $cm^{3}$

Volume of a cylinder can be found with (V = π r 2 h.)

h= height of cylinder ?

radius= 2cm

Substitute the values

10.97= π × $2^{2}$ × h

h= 10.97/12.57

h= 0.85 cm

Therefore, height of the described cylinder is 0.85 cm
