In 5G, One NR Resource Block (RB) contains 12 sub-carriers in frequency domain similar to LTE . In LTE resource block bandwidth is fixed to 180 KHz but in NR it is not fixed and depend on sub-carrier spacing.24 Nis 2019
Read moreWhat is resource block in LTE?
A resource block (RB ) is the smallest unit of resources that can be allocated to a user . The resource block is 180 kHz. wide in frequency and 1 slot long in time.

Common Resource Blocks (CRBs) Common resource blocks are numbered from 0 and upwards in the frequency domain for each subcarrier spacing configuration ‘µ’.5 Kas 2019

The answer is at the end of this article. Physical Resource Block (PRB) = 2*Resource Block = 12 Subcarriers x 14 OFDM in 1ms . RE can deliver 2, 4, 6, 8 bits in QPSK, 16QAM, 64QAM, 256QAM respectively. If we calculate for 64QAM as 6bits since 256QAM not widely spread (check Samsung S7 in T-Mobile).
