I´m pretty sure its magnesium iron silicate.
Answer:
6.022 ×10(index 23) / 7.5 = 0.8293 ×10(index 23)
Explanation:
molar mass of C = 12gmol
therefore in 12g of C there is one mole or an amount of 6.022 ×10(index 23)
∴12g/6.02210(index 23) ×1.6g
Answer:
Sodium (Na): (.5 point)
22.99+35.453=58.433. 22.99/58.433= 39%
Chlorine (Cl): (.5 point)
22.99+35.453=58.433. 35.453/58.433= 61%
Explanation:
The answer is B. Fungi,Protists
Answer:
c) (12×0.9889) + (13×0.01108)
Explanation:
Given data:
Percentage of C-12 = 98.89%
Percentage of C-13 = 1.108%
Atomic mass = ?
Solution:
98.89/100 = 0.9889
1.108/ 100 = 0.01108
Atomic mass = (12×0.9889) + (13×0.01108)
Atomic mass = (11.8668 + 0.144034)
Atomic mass = 12.01084
