Answer:
The answer is
<h2>19.31 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of gold = 475.09g
volume = 24.6 cm³
The density of the gold is
We have the final answer as
<h3>19.31 g/cm³</h3>
Hope this helps you
Answer: 36.53g
Explanation:
First we need to find the amount of NaCl that dissolves in 1L of the solution that produced 5M of NaCl
Molarity = 5M
MM of NaCl = 58.45
Molarity = Mass conc (g/L) / MM
Mass conc. (g/L) of NaCl = Molarity x MM
= 5 x 58.45 = 292.25g
Next, we need to find the amount that will dissolve in 125mL(i.e 0.125L)
From the calculations above,
292.25g of NaCl dissolved in 1L
Therefore Xg of NaCl will dissolve in 0.125L of the solution i.e
Xg of NaCl = 292.25 x 0.125 = 36.53g.
Therefore 36.53g of NaCl will dissolve in 125mL of the solution
The answer would be A) transition metals
The De Broglie wavelength of the muon is calculated to be 4.13 × 10^10 m
We have the following information;
mass of the muon (m)= 206.8 × 9.11 × 10^-31 Kg = 1.88 × 10^-28 Kg
Plank's constant(h) = 6.6 × 10^-34 Js
Velocity of the muon(v) = 8.50×10^5 cm/s or 8500 m/s
From;
λ = h/mv
λ = 6.6 × 10^-34/1.88 × 10^-28 × 8500
λ = 6.6 × 10^-34/1.598 × 10^-24
λ = 4.13 × 10^10 m
