Answer:
2.33 mol C
Explanation:
Step 1: Write the balanced generic chemical equation
3 A ⟶ C + 4 D
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of A to C is 3:1.
Step 3: Calculate the number of moles of C produced from 7 moles of A
We will use the previously established molar ratio.
7 mol A × 1 mol C/3 mol A = 2.33 mol C
The mass numbers of the different isotopes of that element are averaged according to their respective abundances in nature.
Beryllium has four neutrons
Answer:
24.305 to the nearest thousandth.
Explanation:
That is 0.7899*23.985 + 0.10* 24.985+0.1101*25.9825
= 24.305.
The answer is 2300 mg which is equal to one teaspoon of salt
