একটি মাপনী চোঙের সাহায্যে কিভাবে তুমি এক ফোঁটা জলের আপাত আয়তন নির্ণয় করবে​

Answer 1

Answer:

Count out 100 drops, divide the total weight increase measured by your scale, and divide by 100. This calculated answer will be the weight of one drop. If near room temperautre (20 deg C.), divide by the density of water at that temperature, 0.998 gm/ml, and you will have the average volume, in ml.
