For a tablet containing 500. mg of vitamin C, calculate how many ml of 0.095 M NaOH is required to reach the equivalence point.

Gala2k [10]

Answer:

mL of NaOH required =29.9mL

Explanation:

Let us calculate the moles of vitamin C in the tablet:

The molar mass of Vitamin C is 176.14 g/mole

$moles=\frac{mass}{molarmass}=\frac{500mg}{176.14}=\frac{0.5}{176.14}=0.0028$

Thus we need same number of moles of NaOH to reach the equivalence point.

For NaOH solution:

$moles=MolarityXvolume=0.095Xvolume$

$0.00283=0.095Xvolume$

$volume=0.0299L=29.9mL$

Which of the following masses is/are equivalent to seventy billion metric tons?

ale4655 [162]

The correct answer is 70,000 million metric ton.
Seventy billion metric ton = 70, 000,000,000 = 70 * 10^9
70,000 million metric ton = 70,000 * 10^6 = 70 * 10^9
Thus, seventy billion metric ton is equivalent to 70,000 million metric ton.

If the volume is 500 mL, the mass of air is 60g (molar mass of air= 29g/mol), and the temperature is 600 C, what is the pressure

madam [21]

Answer:

The pressure inside the bottle is 92.678 atm.

Explanation:

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

$P$ × $V = n$ × $r$ × $t$
