hope this helps!
Answer:
= 2.33 L
Explanation:
V1/T1 = V2/T2
V1 = 3.0 L
T1 = 78 + 273
= 351 K
At s.t.p the temperature is 273 K and pressure is 1 atm.
V2 = ?
T2 = 273 K
V2 = V1T2/T1
= (3.0 ×273)/351
= 2.33 L
Explanation:
ik it is confusing but that is what i got
Molar mass NaOH =23+16+1=40 g/mol
<span> 0.100 M= 0.100 mol/L
</span>500 ml=0.500 L
0.500L*0.100 mol/L=0.0500 mol NaOH we need to prepare 500 ml solution
0.0500 mol NaOH*40g/1mol=2 g NaOH we need to prepare 500 ml solution
we need 2 g NaOH, dissolve it in small amount of water, and dilute it with water up to 500 mL
