Answer:
hydrogen bonding
Explanation:
The two strands of DNA are held together by hydrogen bonds between complimentary nucleotides.
After the addition of 6.47 mL of 0.303 M HCl. Solution :- lets first calculate the moles of the NaOCl and HCl Moles = molarity *volume in liter Moles of NaOCl = 0.100 mol per L * 0.053 L =0.0053 mol Moles of HCl =0.303 mol per L *0.00647L=0.00196
Nitrogen - hope this helped
Answer:
D) 174 g/mol
Explanation:
Step 1: Given and required data
- Density of the gas (ρ): 7.10 g/L
- Ideal gas constant (R): 0.0821 atm.L/mol.K
Step 2: Convert "T" to Kelvin
We will use the following expression.
K = °C + 273.15
K = 25.0°C + 273.15
K = 298.2 K
Step 3: Calculate the molecular weight (M) of the gas
We will use the following expression derived from the ideal gas equation.
ρ = P × M / R × T
M = ρ × R × T / P
M = 7.10 g/L × (0.0821 atm.L/mol.K) × 298.2 K / 1.00 atm
M = 174 g/mol
