Mass of 2.88x10^-4 mol of ascorbic acid

Lady bird [3.3K]

Molar mass C₆H₈O₆ = 176.12 g/mol

1 mole ------------------ 176.12 g
2.88x10⁻⁴ mole ------- ?

mass = 2.88x10⁻⁴ * 176.12 / 1

mass ≈ 0.05072 g

hope this helps!

Answer:

1 kg=1000g so 2000 g=2kg and 1 liter of water is equal to 1 kg .as a result 2 kg=2l and if consider 1l as 1000 ml we get 2000 ml

the final answer is 2000 g of water equal to 2000 ml

Answer:

2. $V_2=17L$

3. $V=82.9L$

Explanation:

Hello there!

2. In this case, we can evidence the problem by which volume and temperature are involved, so the Charles' law is applied to:

$\frac{V_2}{T_2}=\frac{V_1}{T_1}$

Thus, considering the temperatures in kelvins and solving for the final volume, V2, we obtain:

$V_2=\frac{V_1T_2}{T_1}$

Therefore, we plug in the given data to obtain:

$V_2=\frac{18.2L(22+273)K}{(45+273)K} \\\\V_2=17L$

3. In this case, it is possible to realize that the 3.7 moles of neon gas are at 273 K and 1 atm according to the STP conditions; in such a way, considering the ideal gas law (PV=nRT), we can solve for the volume as shown below:

$V=\frac{nRT}{P}$

Therefore, we plug in the data to obtain:

$V=\frac{3.7mol*0.08206\frac{atm*L}{mol*K}*273.15K}{1atm}\\\\V=82.9L$

Best regards!
