Five beans have a mass of 2.1 g. How many beans are in 0.454 kg of beans.
Dafna11 [192]
One way to do this:
If 5 beans have a mass of 2.1 gms  then each bean is 2.1 ÷ 5 = .42g
0.454kg is the same as 454 g.  So how many .42 are in 454

454 ÷ .42 ≈  1080.95 beans or 1081 rounded to the nearest bean.

For Ethan hunt. Pls check whether this is a correct answer or not.
nevsk [136]
Here, Equation: 2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O

We know, Concentration (c) = Number of moles(n) / Volume (v)

Substitute the given values, 
0.02 = n / 0.3   [ 300 mL = 0.3 L ]
n = 0.3 * 0.02
n = 0.006

Now, According to stoichiometry, There is 1 Molecule of Sodium sulfate produces for every 2 molecules of NaOH.

So, Number of Moles of Na₂SO₄ = 0.006/2 = 0.003

Given mass = Molar mass * Number of moles
M = 142.04 * 0.003
M = 0.426 g

In short, Your Answer would be: 0.426 g

Hope this helps!
