Answer:
14.9 g is the ideal yield of Cu(NO₃)₂
Explanation:
Reactants for the reaction: Cu and AgNO₃
Products: Copper nitrate and Ag
The balanced reaction is: Cu(s) + 2AgNO₃(aq) → 2Ag (s) + Cu(NO₃)₂
As the silver nitrate is in excess, the Cu will be the limiting reagent.
We convert the mass to moles → 5.05 g . 1 mol/ 63.55 g = 0.0794 moles
Ratio is 1:1, so 0.0794 moles will produce 0.0794 moles of Cupper(II) nitrate. We convert the moles to mass, and that value will be the theoretical yield.
0.0794 mol . 187.55 g /1 mol = of Cu(NO₃)₂
Answer:
<h2>3.31 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 23.2 g
volume = final volume of water - initial volume of water
volume = 62 - 55 = 7 mL
We have

We have the final answer as
<h3>3.31 g/mL</h3>

Answer:
The inner diameter of the steam tube is 0.1185 m.
Explanation:

m = mass flow rate
= density of the liquid
V=specific volume =
v = velocity of the liquid
A = area of cross-section
Diameter of the cross-section = d = 2r
Given: m = 18 kg/s, v = 60 m/s,A=?, 


Area of the inner cross section = 

d = 0.1185 m
The inner diameter of the steam tube is 0.1185 m.
