Let no of white keys= W,
Therefore, 7 * 5 +1 + W= 88,
Or, W = 88 -35-1 =52

Figure out how many black keys there are - 7 octives times 5 black keys in each octive is 35, plus the one extra black key is 36. Subtract the number of black keys from the total number of keys to get the number of white keys..

The answer to you question is
88 keys
A to C
7 octaves 1/4
7 white notes and five black notes to an octave
52 white Notes and 36 black Notes
Unless you have a Bosendorfer piano - then you have up to 97 Notes
