Molar mass HCl = 36.5 g/mol and NaOH = 40.0 g/mol
molarity of NaOH = 1.0 M
Volume of NaOH = 20.00 mL in liters : 20.00 / 1000 = 0.02 L
Number of moles NaOH :
n = M * V
n = 1.0 * 0.02
n = 0.02 moles Of NaOH
Finally Molarity of the <span>acid solution
</span>
Volume HCl : 15.0 mL in liters : 15.0 / 1000 = 0.015 L
1 HCl + 1 NaOH = 1 H₂O + 1 NaCl
1 mole HCl --------- 1 mole NaOH
? mole HCl --------- <span> 0.02 moles NaOH
</span>
moles HCl = 0.02 * 1 / 1
= 0.02 moles of HCl
M ( HCl) = n / V
= 0.02 / 0.015
= 1.333 M of HCl
hope this helps!
Three of the functions of proteins are as antibodies, as enzymes and as messengers. As antibodies, they protect the cells from diseases ie they fight diseases. As enzymes, they regulate the chemical reactions within cells, and thirdly they transmit signals as messengers such as hormones do in co-ordinating biological processes. Proteins are so diverse because of their unique 3-D structures which their polymers form from the 20 amino acids available as their building blocks.
Answer:
For O: atomic number = 8 # neutrons = 8
For Al: atomic mass = 27, # electrons = 13
