Answer:
96%
Explanation:
To find the percent yield, we can use this equation
The actual yield of aspirin is 3.0 and the theoretical is 3.14 in this case, so just plug the numbers in.
Thus the percent yield is 96%

Answer:
1. 9.57 × 10^-9 moles.
2. 7.38mol
Explanation:
1.) To find the number of moles there are in the number of particles in an atom, we divide the number of particles (nA) by Avagadro's constant (6.02 × 10^23)
Hence, to find the number of moles (n) of Manganese (Mn), we say:
5.76 x 10^15 atoms ÷ 6.02 × 10^23
5.76/6.02 × 10^(15-23)
= 0.957 × 10^-8
= 9.57 × 10^-9 moles.
2.) Mole = mass/molar mass
Molar mass of sodium chloride (NaCl) = 23 + 35.5
= 58.5g/mol
mole = 431.6 g ÷ 58.5g/mol
mole = 7.38mol
Cmon bro you better then this
Answer:
Metamorphic
Explanation:
Because it describes as a rock framed from other rocks by the action of heat and pressure.
Answer:
Conductors
Explanation:
Metals that are conductors let electric currents flow freely. Insulators have a resistance of a charge to flow through them.
