Answer:
0.33 ml
Explanation:
Formula for density: p = m/V (where p is <em>density</em>, m is <em>mass</em> and V is <em>volume</em>)
So, by applying the above formula:
![19.3 = \frac{6.5}{v}](https://tex.z-dn.net/?f=19.3%20%3D%20%20%5Cfrac%7B6.5%7D%7Bv%7D%20)
![v = 0.33 \: ml](https://tex.z-dn.net/?f=v%20%3D%200.33%20%5C%3A%20ml)
Is soluble in water but not soluble in acetonitrile.
So i think its false
Answer:62.66°C or 235.66K
Explanation:Q=McpT, the energy was given in calories so you first convert to Joules by multiplying the value in calories by 4.184J.
17*4.184=71.128kJ.
71.128kJ=mcpT
71.128kJ=245*4.187*(T-Tm)
Tm is the final temperature of the mixture. The T is the temperature given which should be converted to Kelvin by adding 273...T=32+273=305K.
71128J=245*4.187*(305-Tm)
71128=312873.575-1025.815Tm
1025.815Tm=312873.575-71128
1025.815Tm=241745.58
Tm=241745.58/1025.815
Tm=235.66K
