I'm not 100% sure that this is right but I think D. is correct.
I believe it is radishes, hope this helps have a nice day!!! :)))
Answer:
Empirical Formula:
The empirical formula of a compound is the simplest whole-number ratio of the numbers of the different atoms that compose the molecule of the compound. The empirical formula looks like a molecular formula.
C
2
H
2
and
C
H
are the molecular formula and the empirical formula of acetylene.
The Given Data
The mass of carbon in the compound:
m
C
=
40.6
g
The mass of hydrogen in the compound: {eq}m_H = 5.1 \ \rm...
Standard temperature is 273 K
Standard pressure is 1 atm
We use the ideal gas equation to find out density of nitrogen gas in g/L
Ideal gas equation:
Molar mass of
Pressure = 1 atm
Temperature = 273 K
= 1.25 g/L
Therefore, density of nitrogen gas at STP is 1.25 g/L
Answer:
Molarity of stock HCl solution is 0.89 M
Explanation:
The given problem can be solved using laws of dilution.
According to laws of dilution-
Where, and are initial and final concentration of a solution
and are initial and final volume of a solution
Here, , and
So, = = 0.89 M
Hence, molarity of stock HCl solution is 0.89 M
