How many moles in one gram of Calcium ??

kirill [66]

Answer:

0.0249 moles in 1 g of Ca

Explanation:

Let's think in the molar mass of Ca.

Ca = 40.08 g/mol

So 1 mol weighs 40.08 grams, or in the opposite 40.08 grams is the weigh of 1 mol

The rule of three will be:

40.08 g are contained in 1 mol

1 g may be contained in (1 . 1) / 40.08 = 0.0249 moles

What is the energy of a photon with a frequency of 9.50 x 1013 Hz?

Taya2010 [7]

Answer:

$\huge{6.295 \times {10}^{ - 20} \: J}$

Explanation:

The energy of the photon can be found by using the formula

E = hf

where

E is the energy

f is the frequency

h is the Planck's constant which is

6.626 × 10-³⁴ Js

From the question we have

E = 6.626 × 10-³⁴ × 9.5 × 10¹³

We have the final answer as

$6.295 \times {10}^{ - 20} \: J$

Hope this helps you
