how many dozens of dust particles are in 2.45 g if each particle has a mass of 2.51 x 10^-4 grams...?
I don't have a clue!!!!!!
Thanks Andy
2.45 g x (1 particle/2.51 x 10^-4 g) x (1 dz particles/12 particles) = about 813
2.45 g x (1 particle/2.51 x 10^-4 g) x (1 dz particles/12 particles) = about 813
To determine the number of dozens of dust particles in 2.45 g, we need to divide the total mass by the mass of each particle and then convert the resulting number of particles to dozens.
Step 1: Calculate the number of particles:
Number of particles = Total mass / Mass of each particle
Number of particles = 2.45 g / (2.51 x 10^-4 g)
Number of particles ≈ 9752.99
Step 2: Convert the number of particles to dozens:
1 dozen = 12 particles
Number of dozens = Number of particles / 12
Number of dozens ≈ 9752.99 / 12
Number of dozens ≈ 812.75
Therefore, there are approximately 812.75 dozens of dust particles in 2.45 g.
To determine the number of dozens of dust particles in 2.45 g, we need to divide the total mass by the mass of each particle.
First, let's convert the given mass of each particle from scientific notation to decimal notation:
2.51 x 10^-4 grams = 0.000251 grams
Now, we can calculate the number of particles in 2.45 g:
Number of particles = (Total mass) / (Mass of each particle)
= 2.45 g / 0.000251 g
≈ 9769.323
Since we want to find the number of dozens, we need to divide the number of particles by 12 (since there are 12 particles in a dozen):
Number of dozens = (Number of particles) / 12
≈ 9769.323 / 12
≈ 814.11
Therefore, there are approximately 814.11 dozens of dust particles in 2.45 g.
