1 mole ------------- 6.02 x 10²³ atoms
0.70 moles -------- ( atoms zinc )
atoms platinum = 0.70 x ( 6.02 x 10²³ ) / 1
<span> = </span>4.2 x 10²³ atoms zinc

Answer:
Answer: Hyperoxic alligators show significantly lower breathing rates than their siblings in normoxic and hypoxic groups. Conversely, each breath supports greater oxygen consumption in hyperoxic animals than in other groups. Statistical significance between groups was calculated by ANOVA with post hoc Tukey-Kramer
2.2 x 10^-2
0.055 / 250 = 0.00022 - This would be 2.2 x 10^-4, but the question is asking for percent, not proportion, so multiply by 100% to get the percentage.
0.00022 * 100% = 0.022% = 2.2 * 10^-2
