8.3 x 10^{-3}

Explanation:

Considering the given factors:

A = 1 amu = 1.66 x 10^{-24} g

B = 2amu = 3.32 x 10^{-24} g

Z = 1 (for cubic)

a = 1nm = 10^{-7} cm

M = 1.66 + 3.32

   = 4.98 x 10^{-24}

formula for density

d= \frac{ZM}{a^{3}N_{A}  }

Putting up the values

d = \frac{1* 4.98* 10^{-24} }{10^{-7^{3} } N_{A} }

   = 8.3 x 10^{-3}
