Be sure to answer all parts. Butane gas is compressed and used as a liquid fuel in disposable cigarette lighters and lightweight
Salsk061 [2.6K]

Answer:

The correct answer will be "4.60 g".

Explanation:

The given values are:

Volume of Butane = 7.96 mL

Density = 0.579 g/mL

As we know,

⇒  Mass \ of \ Butane = Density\times Volume

On putting the estimated values, we get

⇒                              =0.579\times 7.96

⇒                              =4.60 \ g

The source of bitterness in dark chocolate is the compound theobromine, an alkaloid present in cocoa beans. In a sample of dark
spin [16.1K]

Answer: 193 mg of theobromine are present in the sample.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given molecules}}{\text {Avogadros number}}=\frac{6.45\times 10^{20}}{6.023\times 10^{23}}=1.07\times 10^{-3}moles

1 mole of theobromine (C_7H_8N_4O_2) weigh = 180 g

1.07\times 10^{-3}moles  of theobromine (C_7H_8N_4O_2) weigh = \frac{180}{1}\times 1.07\times 10^{-3}=0.193g=193mg   (1g=1000mg)

193 mg of theobromine are present in the sample.
