Answer:
1.44 mol
Explanation:
Given data:
Mass of Cu = 46 g
Moles of Ag produced = ?
Solution:
Chemical equation:
Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂
Number of moles of Cu:
Number of moles = mass/ molar mass
Number of moles = 46 g/63.546 g/mol
Number of moles = 0.72 mol
Now we will compare the moles of Cu and silver from balance chemical equation:
Cu : Ag
1 : 2
0.72 : 2×0.72 = 1.44 mol
Thus from 46 g of Cu 1.44 moles of Ag is produced .
Answer:
<h3>F=4k.gm/s^2</h3>
Explanation:
<h3>F=m×a</h3><h3>f=2k.g×2m/s^2</h3><h3>f=4k.gm/s^2</h3>
Answer:
It is expressed as a multiple of one-twelfth the mass of the carbon-12 atom, 1.992646547 × 10−23 gram, which is assigned an atomic mass of 12 units. ... In this scale 1 atomic mass unit (amu) corresponds to 1.660539040 × 10−24 gram.
1.3622052x10^6 you move the . 6 places to the left making it a positive 10^6
