HELP ASAP WILL MARK BRAINLIEST: How many grams of aluminum can be extracted from 5000g of alumina
Lesechka [4]

The grams of aluminium extracted from 5000g of alumina is 2647 grams

<h3>Chemical formula of alumina:</h3>
  • Al₂O₃

Let's calculate the molecular mass of Al₂O₃

Al₂O₃ = 27 × 2 + 16 × 3 = 54 + 48 = 102 g/mol

Therefore,

102 g of Al₂O₃ = 54 g of aluminium  

5000g of Al₂O₃  = ?

mass of aluminium produced = 5000 × 54 / 102

mass of aluminium produced = 270000 / 102

mass of aluminium produced  = 2647.05882353

mass of aluminium produced  = 2647 grams

Easy question please help. DUE IN 15 MINUTES. Calculate the frequency of light that has a wavelength of 9.75 x 10^-7 m.
mart [117]

Answer:

3.077 × 10¹⁴ Hz

Explanation:

f = ?

wavelength = 9.75 × 10-⁷m

using the formula,

c = wavelength × frequency

f = c/wavelength

but c(speed of light) = 3×10⁸m/s

f = 3 × 10⁸/9.75 × 10-⁷

f = 3.077 × 10¹⁴ s-¹
