Answer:
6.273×10²³
Explanation:
hope this is useful friend
I would say <span>4. 40. g at 15°C because kinetic energy is related to temperature and not mass, so the lower temp would give you lower KE</span>
NaOH
Na=23
O=16
H=1
SO,NaOH=23+16+1
NaOH=40g/mol
42% of 40=42/100x40
oxygen is the compound
density=mass/volume
1.30=mass/6
mass=7.8g
Answer:
The answer is D, I would type it out but it is to long and I'm kind of lazy, but anyways! Your answer is D
Hope This Helps!
