Explanation / Answer

1) 2% means 2g in 100ml

We need to prepare 50 ml of agarose gel solution,

So, we need= 2g/2=1g.

So 1 g of agarose is needed to prepare 2% of 50ml agarose gel

2) Preparation of 1X SYBR Safe Stain for 50 ml of agarose gel solution

Dilute 5 µL of 10,000X SYBR Safe Stain concentrate with 50 ml buffer and you will get 1X SYBR safe stain for 50ml agarose gel.
