Density = mass/volume
<span>17.29g / 5.68mL = 3.044g/mL</span>
The equivalent factor used to convert molecules of oxygen to moles of oxygen is Avogadro's number which is 6.022 x10^23. We divide the given number of molecules by Avogadro's number to get the number of moles. In this case, 4.28 * 10^19 molecules divided by <span>6.022 x10^23 is equal to 7.11 x10^-5 moles.</span>
I think the answer will C
Volume of 1 mole of any gas under STP = 22.4 L,
so
0.15 mol*22.4 L/1 mol = 3.36 L of H2
Answer:
C) 35%
Explanation:
Thymine pairs with adenine. If thymine is 15% then so would adenine be 15%. That leaves the reaminder to be 70%. Cytosine pairs with guanine, thereby, they would each be 35%.
