Answer – 0.556 m
Explaination –
Molar mass of Ethanoic acid = 60g/mol
No. Of moles of ethanoic acid = GIVEN MASS
Molar mass / molecular mass
Therefore moles = 2.5/60 .
mass of solvent ( Bezene ) in kg = 75/1000 kg.
Molality = no. of moles of solute
mass of solvent in KG
so after calculating we get Molality = 0.556

I just want to say that you are the best!!!
After reading and applying for your love spell, My boyfriend that left me a few months ago just came back to me last night crying for me to take him back. After a 3 year relationship with my boyfriend, he changed suddenly and stopped contacting me regularly, he would come up with excuses of not seeing me all the time. He stopped answering my calls and my sms and he stopped seeing me regularly. I then started seeing him with different girls several times but every time he would say that he loved me and that he needed some time to think about our relationship. But I couldn’t stop thinking about him so I decided to go online and I saw so many good talks about this spell caster and I contacted him and explained my problems to him. He cast a love spell for me. and After 2days, my boyfriend came back to me and started begging me to forgive him. We moved in together after a few months and he was more open to me than before and he started spending more time with me than his friends. We eventually got married and now have been married happily with a son. Ever since this caster helped me, my husband is very stable, faithful and closer to me than before. Here his contact.
