The Lunar LOK Soyuz massed 9.95 tons. The LK lander was 5.56 tons. Together, they’re 15.51 tons.
The Block D Braking stage for lunar orbit insertion and the initial part of the LK’s landing burn masses 18.2 tons wet and 3.5 tons dry. When combined with the Soyuz and LK, the stack massed 33.71 tons.
The Block G trans lunar injection stage massed 61.8 tons wet and 6 tons dry.
The entire stack, called L3, had a mass of 95.51 tons. But this had to be boosted into orbit first.
Theoretically, a 35 ton launcher could carry the Soyuz, lander, and braking stage into LEO, then two more 35-ton launches could build the halved Block G. Thanks for hearing my TEd talk
