Help me pls answer the yellow boxes.

Calculate the molarity of 48.0 ml of 6.00 m h2so4 diluted to 0.250 l .

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
